- A
FTP traffic (File Transfer Protocol)
Why wrong: FTP traffic is not inspected by the Threat Prevention subscription by default; it requires other security profiles.
- B
Web traffic (HTTP/HTTPS)
Web traffic (HTTP/HTTPS) is inspected by Threat Prevention for exploits, malware, and command-and-control.
- C
VoIP traffic (SIP, H.323)
Why wrong: VoIP traffic (SIP, H.323) is not inspected by the Threat Prevention subscription; it requires application-specific profiles.
- D
Email traffic (SMTP, POP3, IMAP)
Email traffic (SMTP, POP3, IMAP) is inspected by Threat Prevention for malicious attachments and links.
- E
Database traffic (SQL, Oracle)
Why wrong: Database traffic (SQL, Oracle) is not inspected by the Threat Prevention subscription; it requires other security profiles.
PCNSA Palo Alto Networks Platforms and Architecture Practice Question
This PCNSA practice question tests your understanding of palo alto networks platforms and architecture. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network administrator is configuring a Palo Alto Networks firewall in a datacenter. Which TWO traffic types can be inspected by the firewall's Threat Prevention subscription? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Web traffic (HTTP/HTTPS)
The Threat Prevention subscription on Palo Alto Networks firewalls is designed to inspect web traffic (HTTP/HTTPS) using signatures for exploits, malware, command-and-control, and phishing, and email traffic (SMTP, POP3, IMAP) for malicious attachments, links, and spam. It does not include inspection for FTP, VoIP (SIP, H.323), or database protocols (SQL, Oracle) by default; those traffic types require other security profiles such as Application Security, Data Filtering, or specific decryption policies. Therefore, the correct answers are B and D.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume all application-layer traffic (like FTP, VoIP, or database) is equally inspected by Threat Prevention, but Palo Alto Networks separates inspection responsibilities: Threat Prevention is specifically designed for web and email traffic, while other traffic types are handled by separate profiles like Application Security or Data Filtering.
Detailed technical explanation
How to think about this question
Under the hood, the Threat Prevention subscription leverages a unified content-ID engine that decodes HTTP/HTTPS streams and email MIME structures to extract files and URLs for signature matching and WildFire analysis. In real-world deployments, inspecting HTTPS traffic requires SSL decryption to be enabled, as the firewall cannot inspect encrypted payloads without a decryption policy, making web traffic a primary focus for threat prevention.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
